Abstract: A closure for a pressurized container, such as a coolant radiator, provides overflow protection by means of a tube connecting the highest point of the container with the filler neck. The end of the tube in the filler neck is closed by a cap having a high pressure relief valve. The closure cap also contains a low pressure relief valve connected to the tube which, together with the high pressure relief valve, maintains a pressure balance in the container without substantial change in the amount of fluid therein. Both valves are connected directly to a bleed line to atmosphere or a reservoir. The tube and filler neck together serve to regulate the pressure in the container and to provide a maximum fluid level within the container.

Abstract: A one-piece molded end closure has a pull ring spaced from a main panel having an annular flange extending therefrom. When the end closure is frangible through having score lines formed in the main panel, the pull ring is connected by a tenon adjacent a score point, which is the junction of two score lines and inside of the inner diameter of the pull ring, so that pulling on the pull ring, which is substantially parallel to the main panel, starts rupturing of the two score lines. The end closure also may be a plug type having a friction fit within a container whereby there are no score lines; the pull ring is still used to remove the end closure from the open end of the container. The method and apparatus for molding enable production of the end closure as one piece without any tearing of the pull ring or rupturing of the score lines when the end closure is removed from the molding apparatus.
